Some of this "far out there" stuff isn't so far out there when you factor in that time is not linear and the possibility of a multiverse. Quantum entanglement is a proven state. As is superposition. How those things come to be is not factually known, only theorized.
We really do not know as much about our existance in time and space as most of us pretend we do.
Linear in which direction, if there is a forward and backward then there is also a lateral movement. When examining the progression of the earth from the beginning of the solar system until now you might have 4B years. We are alive for 100 years so we are a little short of being a witness to the whole event.
We can't wind ourselves back to that era but we do have living examples of how physics operates and those laws remain consistent throughout the known universe. It is a matter of using the best model to support what you are exploring. The Universe is finite and it either operates one way or another because a known change is going to take place because we are in motion already so there is a past and a future already (for that part)
The more complicated something is establishes a 'level of difficulty' that also includes 'size'. The earth could be explored for 100 years and an industrious person could solve all the questions in that time. Start at the moon and expand outwards and 100 years means nothing. If the universe is 1,000,000 times more complex an industrious person will be there for 100,000,000 years before he is as wise about that as he was about the earth at the 100 year mark.
The fate of the universe can also go two ways from where we currently are as expansion is the current direction. If we keep expanding the the ability of new stars forming from the remains of exploded stars the the number of new stars is going to be less than the number of new starts starting to give off light which is a sign of a certain amount of mass art a certain temperature. If the number drops to zero and expansion is still taking place we would have just entered a black-hole, rather than a place of so much gravity light can't escape it is a place where the gravity is so small that nothing is attracted to each other. From there you would need the multiverse concept to begin to come into play as the way anything ever came out of that condition. If it takes you 100,000,000 years to explore the universe that is shedding light then when it foes dark that should tahe 100B years to do the same for that place. The end of that would put you at the beginning of a place that would take you 100T years to fully understan in the literal version. Theory tells you it is there, it doesn't come with the nuts and bolts, this earth is what we have the nuts and bolts for so that is where we can combine knowledge with the power to make literal changes.
(BTW if the earth and moon collided why would that not be the final configuration rather than everything rejoining into 2 bodies. Perhaps the earth became unbalanced early on and the rapid spin shed the moon via a series of massive volcanoes when the earth was still small enough to spin that fact. The tidal lock that came later would be the moon suffering the same thing but the volcanoes it had on the near side was the moon's heavy metals and when it blew that material was sent to the earth rather than falling back to the moon.)
In the spiritual side I wonder what Enoch was like to talk to at an evening down at the pub?
If mass contracts when it cools then the expansion should slow down on it's own as soon as more starts die than are born as that is a cooling phase and an implosion could happen 40B years after that starts to happen.
groan. Now everyone is going to get in on the act and we'll have to read tongs of utensil puns. Sheesh!
Keeps the minions away from the stuff that might burn them. Like chumming the water before setting the nets out.
